Universal relations applied to proto-neutron star generated gravitational waves from three-dimensional core collapse supernova simulations
R. Daniel Murphy, Anthony Mezzacappa, Colter J. Richardson +3
Using asteroseismology techniques, several relations have been developed that relate the quasi-normal, non-radial oscillation mode frequencies of the proto-neutron star (PNS) to th…
Linear Gravitational Wave Memory Through the Window of Core-Collapse Supernovae
Colter J. Richardson, Anthony Mezzacappa, Haakon Andresen +1
Low-frequency gravitational waves ( 50 Hz) from core-collapse supernovae are becoming more important for current and future gravitational wave studies. This frequency…
Gravitational Waves as a Probe of Core Collapse Supernova Progenitor Structure
R. Daniel Murphy, Elle Brinkman, Colter J. Richardson +5
We present the gravitational wave predictions from two-dimensional core collapse supernova (CCSN) simulations initiated from two nearly identical progenitors that have significantl…
Detectability of SASI activity in supernova neutrino signals
Zidu Lin, Cecilia Lunardini, Michele Zanolin +2
We introduce a novel methodology for establishing the presence of Standing Accretion Shock Instabilities (SASI) in the dynamics of a core collapse supernova from the observed neutr…
